FIELD OF THE INVENTION

[0001] The present invention is related to new substituted pyrrolidine derivatives of formula I. Said compounds are preferably for use as pharmaceutically active compounds. Specifically, pyrrolidine derivatives of formula I are useful in the treatment and/or prevention of neurodegenerative disorders, diseases associated with polyglutamine tracts, epilepsy, ischemia, infertility, cardiovascular disorders, renal hypoxia, hepatitis and AIDS. Said pyrrolidine derivatives display a modulatory and most notably a down-regulating—up to an inhibitory—activity with respect to the cellular death agonist Bax and/or the activation pathways leading to Bax and allows therefore to block the release of cytochrome c. The present invention is furthermore related to novel pharmaceutically active substituted pyrrolidine derivatives as well as to methods of their preparation.

BACKGROUND OF THE INVENTION

[0002] Apoptosis denotes the complex contortions of the membrane and organelles of a cell as it undergoes the process of programmed cell death. During said process, the cell activates an intrinsic suicide program and systematically destroys itself in a controlled manner or by a self-regulated process. The following series of events can be observed:

[0003] The cell surface begins to bleb and expresses pro-phagocytic signals. The whole apoptotic cell then fragments into membrane-bound vesicles that are rapidly and neatly disposed of by phagocytosis, so that there is minimal damage to the surrounding tissue.

[0004] The cell then separates from its neighbors.

[0005] The nucleus also goes through a characteristic pattern of morphological changes as it commits genetic suicide. The chromatin condenses and is specifically cleaved to fragments of DNA.

[0006] Neuronal cell death plays an important role in ensuring that the nervous system develops normally. It appears that the death of developing neurons depends on the size of the target that they innervate: cells with fewer synaptic partners are more likely to die than those that have formed multiple synapses. This may reflect a process, which balances the relative number of pre- to postsynaptic neurons in the developing nervous system. Although neuronal cell death was assumed to be apoptotic, it was only recently that neurons in developing rodent brain were conclusively shown to undergo apoptosis as classified by morphology and DNA fragmentation.

[0007] Neuronal death occurs via either apoptotic or necrotic processes following traumatic nerve injury or during neurodegenerative diseases. Multiple components are emerging as key players having a role in driving neuronal programmed cell death. Amongst the components leading to neuronal apoptosis are protein members belonging to the Bcl-2 family (see Jacobson, M. D. 1997. Current Biology 7:R 277-R281; Kroemer, G. C. 1997. Nature Medicine: 614-620; Reed, J. C. 1997. Nature 387:773-776).

[0008] The entire Bcl-2 family comprises both anti-apoptotic (Bcl-2, Bcl-x_(L), Bcl-w, Mcl-1, A1, NR-13, BHRF1, LMW5-HL, ORP16, KS-Bcl-2, E1B-19K, CED-9) and pro-apoptotic (Bax, Bak, Bok, Bik, Blk, Hrk, BNIP3, Bim_(L), Bad, Bid, EGL-1) molecules (see Kelekar, A., and C. B. Thomp-son 1998. Trends in Cell Biology 8:324-330). The specific member thereof, i.e. the first found, Bcl-2 is a 26 kDa protein that localizes to the mitochondrial, endoplasmatic reticulum and perinuclear membranes. The Bcl-2 family proteins can form homo- and heterodimers that involve amino acid sequences known as Bcl-2 homology (BH) domains. So far, four of said domains (BH1 to 4) have been identified, the BH3 having been attributed a particularly prominent role in view of the death-promoting cascade. Said BH3 domain of the pro-apoptotic members appears to be required for the interaction between anti and pro-apoptotic molecules. The principal site of action of some of the Bcl-2 family members seems to be the mitochondria. Mitochondria have been shown to play a major role in many types of apoptosis. In particular, this organelle has been shown to release Apoptosis Inducing Factor and cytochrome c, a hemoprotein which is bound to the outer surface of the inner mitochondrial membrane. Said cytochrome c has been shown to trigger caspase 9 activation through Apaf-1/caspase 9 complex formation. Bcl-2 family members play a key role in regulating cytochrome c release. While Bcl-2 and Bcl-x_(L) have been shown to suppress cytochrome c release, Bax has been found to stimulate this event both in vitro using isolated mitochondria as well as in intact cells following heterologous expression (Martinou et al.; The Journal of Cell Biology, 128, 1995, 201-208). The mechanisms by which these proteins perform their function are currently unknown. The three-dimensional structure of Bcl-xL and Bid revealed structural similarities between these proteins and the channel-forming domains of the bacterial toxins colicins and diphtheria toxins. Consistent with such structural similarity, some members of this family including Bax were also found able to form ion channels in synthetic lipid membranes.

[0009] Studies performed with Bax-deficient mice led to the conclusion that Bax plays a promi-nent role within the apoptosis pathways, notably in neuronal apoptosis. Bax is viewed to be essential for apoptosis induced by NGF deprivation in neonatal sympathetic neurons or for apoptosis induced in cerebellar granule cells by potassium deprivation from the culture medium. Moreover, it was found that in the Bax-deficient mice (knock-out) neonatal motoneurons from the facial nucleus can survive following axotomy (see Deckwerth, T. L., Elliott J. L., Knudson C. M. et al. 1996. Neuron 17,401-41). Hence, the inhibition of the Bax activity leading to the prevention of cytochrome c release from mitochondria during apoptosis, is viewed to be useful to protect neurons and also other cell types from various cell death stimuli.

[0010] In WO 97/01635 (Neurex Corp.) the inhibition of apoptosis in an effort to promote cell survival is suggested to be achieved by introducing into the cell a chimeric gene containing a polynucleotide encoding a Bax-ω-polypeptide (a splice variant of the Bax gene, which displays—in contrast to Bax—an anti-apoptotic activity) being operably linked to a promoter effective to cause transcription of the polynucleotide in the cell. It is reported that the expression of the Bax-ω-polypeptide is effective to inhibit apoptosis in the cell. Perez et al. in Nat. Genet. 1999, 21(2), 200-203 have indicated that apoptosis plays a fundamental role in follicular atresia and they suggest to selectively disrupt the Bax function in order to extend the ovarian lifespan.

[0011] Bax down-regulation up to inhibition could indeed represent an interesting therapy for all diseases associated with apoptosis, including neurodegenerative diseases (e.g. Alzheimer's disease, Parkinson's disease, diseases associated with polyglutamine tracts including Huntington's disease, spino-cerebellar ataxias and dentatorubral-pallidoluysian atrophy; amyotrophic lateral sclerosis, retinitis pigmentosa and multiple sclerosis, epilepsy), ischemia (stroke, myocardial infarction and reperfusion injury), infertility (like premature menopause, ovarian failure or follicular atresia), cardiovascular disorders (arteriosclerosis, heart failure and heart transplantation), renal hypoxia, hepatitis and AIDS.

[0012] Hence, it is an objective of the present invention to provide compounds enabling the treatment of apoptosis-related disorders, including notably the above mentioned diseases.

[0013] It is specifically an objective of the present invention to provide a treatment of apoptosis related disorders by specifically regulating the Bax function, e.g. by modulating, in particular by down-regulating up to inhibiting, the Bax function or by down-regulating, up to inhibiting, the Bax activation.

[0014] It is notably an objective of the present invention to provide small molecule pharmaceuticals, more specifically non-protein or non-peptide molecules that avoid essentially all of the drawbacks arising from the use of large peptides or proteins (e.g. restricted bio-availability as well as problems arising from in vivo intolerance thereto), however, which are suitable for the treatment of a number of diseases associated with abnormal apoptosis. It is particularly an objective of the present invention to provide small molecule chemical compounds being suitable Bax modulators (e.g. compounds inhibiting the Bax function or inhibiting the Bax activation) so to be available for a convenient method of treating diseases involving abnormal apoptosis. Moreover, it is an objective of the present invention to provide methods for preparing said small molecule chemical compounds. It is furthermore an objective of the present invention to provide a new category of pharmaceutical formulations for the treatment of a host of diseases. It is finally an objective of the present invention to provide a method of treating diseases that are caused by abnormal apoptosis.

[0296] Thereby, the most preferred compounds are those which are selected from the group consisting of:

[0305] A further aspect of the present invention is related to the use of the pyrrolidine derivatives according to formula I for the preparation of pharmaceutical compositions for the treatment of diseases including Alzheimer's disease, Parkinson's disease, diseases associated with polyglutamine tracts including Huntington's disease, spinocerebellar ataxias and dentatorubral-pallidoluysian atrophy; amyotrophic lateral sclerosis, Crohn's disease, retinitis pigmentosa and multiple sclerosis, epilepsy), ischemia (stroke, myocardial infarction and reperfusion injury), infertility (like premature menopause, ovarian failure or follicular atresia), cardiovascular disorders (arteriosclerosis, heart failure and heart transplantation), renal hypoxia, hepatitis and AIDS.

[0306] According to a preferred embodiment, the above cited diseases or disease states are treated by the modulation of the Bax function, or the modulation (e.g. the inhibition) of the activation or expression of Bax, respectively, via the use of compounds of formula I, whereby the term Bax function notably comprises the actually active form of Bax as an oligomer (see B. Antonsson et al. in Biochem. J., Vol. 345, 2000, pages 271-278). Through the modulation of the Bax function, a convenient method of treatment of disorders mediated by Bax is expected, including in particular neuronal disorders and/or disorders of the immune system. Said modulation could notably involve the inhibition of the activity (activation) and/or of the expression of Bax. Also, said modulation of the Bax function or activity could actually comprise the inhibition or disruption for instance of the Bid interaction with Bax, which has been shown to play a role within the context of the Bax activation leading to cytochrome c release (see J. C. Martinou et al. in The Journal of Cell Biology, Vol. 144, No. 5, Mar. 8, 1999, pages 891-901). As a result of the inhibition of the Bax activation by Bid upon using the compounds according to formula I, the cytochrome c release could be inhibited or essentially blocked, thus providing a convenient means to modulate the above described apoptosis pathways. As a result, by said modulation of the apoptosis pathways a whole variety of disorders associated with abnormal apoptosis is expected to be treated.

[0307] It is reported herein that the compounds of formula I are suitable to be used as a medicament, i.e. they are suitable for use in treating diseases, like disorders of the autoimmune system and neuronal system of mammals, notably of human beings. More specifically, the compounds according to formula I, alone or in the form of a pharmaceutical composition, are useful for the modulation, in particular for the inhibition, of the Bax function and/or the Bax activation. More specifically, the compounds according to formula I, alone or in the form of a pharmaceutical composition, are useful for the treatment or prevention of disorders associated with abnormal expression or activation of Bax. The compounds according to formula I could be employed alone or in combination with further pharmaceutical agents. The compounds of formula I are suitable to be used as a medicament alone or in the form of a pharmaceutical composition together with suitable carriers, diluents or excipients. The compounds of formula I are suitable to be used for the preparation of orally administrated pharmaceutical compositions.

[0308] Thus, according to the present invention, compounds pursuant to formula I are particularly useful for the treatment or prevention of immuno- and/or neuronal-related diseases or pathological states in which preferably the modulation, in particular the inhibition, of the Bax function and/or the Bax activation plays a crucial role, such as neurodegenerative diseases (e.g. Alzheimer's disease, Parkinson's disease, diseases associated with polyglutamine tracts including Huntington's disease, spinocerebellar ataxias and dentatorubral-pallidoluysian atrophy; amyotrophic lateral sclerosis, Crohn's disease, retinitis pigmentosa and multiple sclerosis, epilepsy), ischemia (stroke, myocardial infarction and reperfusion injury), infertility (like premature menopause, ovarian failure or follicular atresia), cardiovascular disorders (arteriosclerosis, heart failure and heart transplantation), renal hypoxia, hepatitis and AIDS.

[0309] Still a further aspect of the present invention is related to the actually novel pyrrolidine compounds of formula I. Some very few compounds have actually been disclosed prior to the filing of the present application, without any medical use though. Said known compounds of formula I are those, wherein

[0310] X is (═CH₂), A is —(C═O)—O—, R¹ is a t-butyl group and B is —(C═O)—NMe₂ (Tetrahedron 53(2), 539, 1997); —(C═O)—NHMe (WO 95/47718); —(C═O)—NH—CH(Me)-(C═O)—NH—CH(Me)—COOH (WO 95/47718); or —(C═O)—NH—CH(COOCH₂-Ph)—CH₂—COOPh (Tetrahedron 48(31), 6529, 1992).

[0311] X is (═CHR⁶) with R⁶ being cyclohexylmethyl, A is —(C═O)—O—, R¹ is a t-butyl group and is —(C═O)—NH-t-butyl (Biorg. Chem. Lett. 3(8), 1485, 1993).

[0312] X is C₁-C₂₀ alkylidene, A is —(C═O)—O—, R¹ is a t-butyl and B is

[0313] wherein R is C₁-C₁₂ alkyl and Hal is Cl, Br, J. Said compounds are disclosed in DE-1,932,823 as intermediates.

[0314] X is C₁-C₂₀ alkylidene, A-R1 is a protective group and B is

[0315] with R being H or C₁-C₁₂ alkyl (GB-1,118,306)

[0316] Also excluded are the following compounds:

[0317] which is disclosed in WO 00/08015 as being an FSH agonist.

[0318] which is disclosed in Bioorg Med. Chem. (1996), 4(8), pp.1365-77 as being useful for the treatment of infections.

[0319] wherein: Pin is —NH—CH[C₆H₃(OMe)₂]C₆H₄OCHCO-Gly-NH(CH₂)₆NH-MA/DMA-polyethylene pin (Tetrahedron Letters, Vol. 36 (1995) No.28, pp.5081-5084). No biological activity is disclosed for said molecule.

[0320] The above two compounds are disclosed in J. Med. Chem, 29 (1986) pp.959-971 for their ability to reverse electroconvulsive shock-induced amnesia in rodents.

[0321]Int. J. Pept. Protein Res. (1982), 20(5), pp.438-42.). No biological activity is disclosed for said molecule.

[0322] Hence, the novel compounds are those of the formula I, wherein the above mentioned known compounds are excluded.

[0323] Still a further object of the present invention is a process for preparing the pyrrolidine derivatives according to formula I.

[0324] The pyrrolidine derivatives exemplified in this invention can be prepared from readily available starting materials using the following general methods and procedures. It will be appreciated that where typical or preferred experimental conditions (i.e. reaction temperatures, time, moles of reagents, solvents, etc.) are given, other experimental conditions can also be used unless otherwise stated. Optimum reaction conditions may vary with the parti-cular reactants or solvents used, but such conditions can be determined by one skilled in the art by routine optimisation procedures. Generally, the pyrrolidine derivatives according to the general formula I could be obtained by several processes, using both solution-phase and solid-phase chemistry protocols. Depending on the nature of A, B, and X, certain processes will, in some instances, be preferred over others, and it is assumed that the choice of the most suitable process will be obvious to the practitioner skilled in the art.

[0325] According to one process, pyrrolidine derivatives according to the general formula I, whereby the substituent B is C(O)—NR⁸R⁹, with R⁸ and R⁹ being defined as above, are prepared from the corresponding suitably N-protected 4-substituted pyrrolidine derivatives II, whereby the substituent X is as above defined, by solution-phase chemistry protocols such as described in the Examples and shown in Scheme 1, below. The suitably N-protected 4-substituted pyrrolidine derivatives II are first reacted with primary or secondary amines III, whereby the substituents R⁸ and R⁹ are as above defined, using conditions and methods well known to those skilled in the art to prepare an amide from an amine and a carboxylic acid or a carboxylic acid derivative, using standard peptide coupling agents, such as e.g. DIC, EDC, THTU, DECP, or others, to yield compounds of formula IV. Removal of the N-protecting group using the appropriate deprotection agents produces deriva-tives of formula V. These can be treated with acylating agents of general formula VI, whereby the substituent R¹ is as above defined, while LG could be any appropriate leaving group. Preferred acylating agents VI are acid chlorides (VIa), used in conjunction with a tertiary amine base, or carboxylic acids (VIb), used in conjunction with a peptide coupling agent, e.g. from the above mentioned group, to yield the products of general formula I, with B being defined as C(O)N⁸R⁹ (Ia).

[0326] Other derivatives of formula I are prepared using known modifications to the Scheme 1 reaction sequence. Compounds of formula I wherein A is different from the carbonyl functionality are prepared by replacing formula VI compounds with compounds containing the appropriate functional groups, e.g. sulfonyl chlorides, isocyanates, isothiocyanates, chloroformates, substituted alkyl halides, or others to yield sulfonamide, urea, thiourea, carbamate, substituted alkyl derivatives, or others, respectively.

[0327] Compounds of formula II, whereby the substituent X is CR⁶R⁷, and R⁶ and R⁷ are as above defined, can be prepared from compounds of general formula VII by Wittig-type reactions with anions of phosphoranes such as VIIIa and/or of phosphonates such as VIIIb, followed by saponification of the ester function using standard synthetic techniques, as hereinafter described in the Examples and shown in Scheme 2.

[0328] Compounds of general formula VII can be prepared from commercially available, suitably N-protected 4-hydroxyproline X, by a reaction sequence consisting of oxidation and esterification, using standard synthetic techniques as hereinafter described in the Examples and shown in Scheme 3.

[0329] Compounds of formula II, wherein the substituent X is NOR⁶ or NNR⁶R⁷, and R⁶ and R⁷ are as above defined, can be prepared from compounds of general formula XI by reaction with substituted hydroxylamines XIIa and/or substituted hydrazines and/or hydrazides XIIb using standard synthetic techniques as hereinafter described in the Examples and shown in Scheme 4.

[0330] Compounds of formula XIIa are commercially available or prepared by standard synthetic techniques as hereinafter described in the Examples. Compounds of formula II with X═S are accessible from the corresponding suitably protected ketopyrrolidine intermediates VII through standard functional group interconversion methods well known to the person skilled in the art, such as, e.g., by treatment with Lawesson's reagent or others (Pedersen, B. S. et al.; Bull. Soc. Chim. Belg. 1978, 87,223), followed by saponification.

[0331] According to another process, pyrrolidine derivatives according to the general formula I, whereby the substituent B is a heterocyclic residue B1 as above defined, and the substituents are as above defined, are prepared from the corresponding suitably N-protected 4-substituted pyrrolidine derivatives II, whereby the substituent X is as above defined, by solution-phase chemistry protocols such as described in the Examples and shown in Scheme 5, below. The starting suitably N-protected 4-substituted pyrrolidine derivatives II are first reacted with ortho-substituted primary anilines of general formula XIII, whereby the substituents Q, Z, E, Y, and R¹¹ are as above defined, using standard peptide coupling agents, such as DIC, EDC, THTU, DECP, or others, followed by exposure to dilute weak acid, such as acetic acid, in a suitable organic solvent, such as DCM, to promote cyclisation yielding compounds of formula XIV. Removal of the N-protecting group using the appropriate deprotection agents produces cyclic derivatives of formula XV. These can be treated with acylating agents of general formula VI, whereby the substituent R¹ is as above defined, while LG could be any appropriate leaving group. Preferred acylating agents VI are acid chlorides (Via), used in conjunction with a tertiary amine base, or carboxylic acids (VIb), used in conjunction with a peptide coupling agent, e.g. from the abovementioned group, to yield the products of general formula I, with B being defined as B1 (Ib).

[0332] Other derivatives of formula I are prepared using known modifications to the Scheme 5 reaction sequence. Compounds of formula I wherein A is different from the carbonyl functionality are prepared by replacing formula VI with compounds containing the appropriate functional groups, e.g. sulfonyl chlorides, isocyanates, isothiocyanates, chloroformates, substituted alkyl halides, or others to yield sulfonamide, urea, thiourea, carbamate, substituted alkyl derivatives, or others, respectively.

[0333] According to another general process, summarized in Scheme 6, pyrrolidine derivatives according to the general formula I, whereby the substituents A, B, X, and R¹ are as above defined, are prepared from compounds of formula XVI, using the synthetic techniques as outlined in Schemes 2 and 4. As further shown in Scheme 6, compounds of formula XVI are accessible either from XI, following, e.g., the synthetic methodologies introduced in Schemes 1 and 5, or from Ic through hydrolysis of the methyloxime moiety, e.g. under mild hydrolysis conditions as described hereinafter in the Examples. This present synthetic strategy is most preferred when X is NOH or NNR⁶R⁷, whereby the substituents R⁶ and R⁷ are as above defined.

[0334] According to yet another process, pyrrolidine derivatives according to the general formula I, whereby the substituents A, B, X, and R¹ are as above defined, are prepared from the corresponding suitably N-protected 4-substituted pyrrolidine derivatives II, whereby the substituent X is above defined, by a solid-phase protocol such as described in the examples and shown in Scheme 7, below. The N-Boc-protected 4-substituted pyrrolidine derivative II is reacted e.g. with Kaiser oxime resin using standard carbodiimide-mediated coupling conditions well known to the practitioner skilled in the art, followed by Boc-deprotection with dilute TFA in DCM, or with BF₃.OEt₂ in dilute HOAc in DCM, to give compound M. The latter compound can be treated with acylating agents of general formula VI, whereby the substituent R¹ is as above defined, while LG could be any appropriate leaving group. Preferred acylating agents VI are acid chlorides (VIa), used in conjunction with a tertiary amine base, or carboxylic acids (VIb), used in conjunction with a peptide coupling agent, e.g. DIC or EDC, to yield products of general formula XX.

[0335] Compounds of formula I wherein A is different from the carbonyl functionality are pre-pared by replacing formula VI with compounds containing the appropriate functional groups, e.g. sulfonyl chlorides, isocyanates, isothiocyanates, chloroformates, substituted allyl halides, or others to yield sulfonamide, urea, thiourea, carbamate, substituted alkyl derivatives, or others respectively.

[0336] In order to obtain the final compounds of general formula I, the linkage to the resin is cleaved by prolonged treatment with amines of general formulae III or XIII and low percentages of a weak acid, such as HOAc. The cycles within the below Scheme 7 illustrate the resign beads to which the corresponding compounds are linked during the solid phase synthesis. Other derivatives of formula I are prepared using known modifications to, or variations of; the Scheme 7 reaction sequence. Further to the above mentioned Kaiser oxime resin, other suitable reagents, notably resins, known to a person skilled in the art, could be employed for the solid-phase synthesis of compounds of general formula I.

[0337] The reaction sequences outlined in the above Schemes provides enantiomerically pure compounds of formula I, if enantiomerically pure starting materials are used (R) as well as (S) enantiomers can be obtained depending upon whether (R) or (S) forms of commercially available compounds of formulas II, III, VI, and/or X were used as the starting materials.

[0338] However, the reaction sequences outlined in the above Schemes usually provides mixtures of (E) and (Z) isomers with respect to the substituents on the exocyclic double bond of the pyrrolidine ring. In all cases studied, these (E)/(Z)-isomers could be separated by standard chromatography techniques well known to the person skilled in the art, such as by reversed phase hi-pressure liquid chromatography (HPLC) or silica gel flash chromatography (FC). The assignment of the absolute configuration of the exocyclic double bond was performed using NMR-techniques well described in the literature as will be known to the practitioner skilled in the art (for configuratiornal assignements of e.g. oxime functionalities, see e.g. E. Breitmaier, W. Voelter Carbon-13 NMR Spectroscopy, 3rd Ed, VCH, 1987, p. 240).

[0339] According to a flirter general process, compounds of formula I can be converted to alternative compounds of formula I, employing suitable interconversion techniques such as hereinafter described in the Examples.

[0340] If the above set out general synthetic methods are not applicable for obtaining compounds according to formula I and/or necessary intermediates for the synthesis of compounds of formula I, suitable methods of preparation known by a person skilled on the art should be used. In general, the synthesis pathways for any individual compound of formula I will depend on the specific substitutents of each molecule and upon the ready availability of intermediates necessary; again such factors being appreciated by those of ordinary skill in the art. For all the protection, de-protection methods, see Philip J. Kocienski, in “Protecting Groups”, Georg Thieme Verlag Stuttgart, New York, 1994 and, Theodora W. Greene and Peter G. M. Wuts in. “Protective Groups in Organic Synthesis”, Wiley-Interscience, 1991.

[0341] Compounds of this invention can be isolated in association with solvent molecules by crystallization from evaporation of an appropriate solvent. The pharmaceutically acceptable acid addition salts of the compounds of formula I, which contain a basic center, may be prepared in a conventional manner. For example, a solution of the free base may be treated with a suitable acid, either neat or in a suitable solution, and the resulting salt isolated either by filtration or by evaporation under vacuum of the reaction solvent. Pharmaceutically acceptable base addition salts may be obtained in an analogous manner by treating a solution of compound of formula I with a suitable base. Both types of salt may be formed or interconverted using ion-exchange resin techniques.

[0342] If the above set out general synthetic methods are not applicable for the obtention of compounds of formula I, suitable methods of preparation known by a person skilled in the art should be used.

[0343] A final aspect of the present invention is related to the formulations containing the active compounds according to formula I. When employed as pharmaceuticals, the pyrrolidine derivatives of the present invention are typically administered in the form of a pharmaceutical composition. Hence, pharmaceutical compositions comprising a compound of formula I and a pharmaceutically acceptable carrier, diluent or excipient therefore are also within the scope of the present invention. A person skilled in the art is aware of a whole variety of such carrier, diluent or excipient compounds suitable to formulate a pharma-ceutical composition. Also, the present invention provides compounds for use as a medi-cament. In particular, the invention provides the compounds of formula I for use as Bax antagonist, for the treatment of disorders of mammals, notably of human beings associated with inappropriate cell death, including neurodegenerative disorders, diseases associated with polyglutamine tracts, epilepsy, ischemia, infertility, cardiovascular disorders, renal hypoxia, hepatitis and AIDS, either alone or in combination with other medicaments, notably in combination with further Bax inhibitors.

[0344] The compounds of the invention, together with a conventionally employed adjuvant, carrier, diluent or excipient may be placed into the form of pharmaceutical compositions and unit dosages thereof, and in such form may be employed as solids, such as tablets or filled capsules, or liquids such as solutions, suspensions, emulsions, elixirs, or capsules filled with the same, all for oral use, or in the form of sterile injectable solutions for parenteral administration (including subcutaneous use). Such pharmaceutical compositions and unit dosage forms thereof may comprise ingredients in conventional proportions, with or without additional active compounds or principles, and such unit dosage forms may contain any suitable effective amount of the active ingredient commensurate with the intended daily dosage range to be employed.

[0345] When employed as pharmaceuticals, the pyrrolidine derivatives of this invention are typically administered in the form of a pharmaceutical composition. Such compositions can be prepared in a manner well known in the pharmaceutical art and comprise at least one active compound. Generally, the compounds of this invention are administered in a pharmaceutically effective amount. The amount of the compound actually administered will typically be determined by a physician, in the light of the relevant circumstances, including the condition to be treated, the chosen route of administration, the actual compound administered, the age, weight, and response of the individual patient, the severity of the patient's symptoms, and the like.

[0346] The pharmaceutical compositions of these inventions can be administered by a variety of routes including oral, rectal, transdermal, subcutaneous, intravenous, intramuscular, and intranasal. Depending on the intended route of delivery, the compounds are preferably formulated as either injectable or oral compositions. The compositions for oral administration can take the form of bulk liquid solutions or suspensions, or bulk powders. More commonly, however, the compositions are presented in unit dosage forms to facilitate accurate dosing. The term “unit dosage forms” refers to physically discrete units suitable as unitary dosages for human subjects and other mammals, each unit containing a predetermined quantity of active material calculated to produce the desired therapeutic effect, in association with a suitable pharmaceutical excipient. Typical unit dosage forms include prefilled, premeasured ampoules or syringes of the liquid compositions or pills, tablets, capsules or the like in the case of solid compositions. In such compositions, the pyrrolidine compound is usually a minor component (from about 0.1 to about 50% by weight or preferably from about 1 to about 40% by weight) with the remainder being various vehicles or carriers and processing aids helpful for forming the desired dosing form.

[0347] Liquid forms suitable for oral administration may include a suitable aqueous or nonaqueous vehicle with buffers, suspending and dispensing agents, colorants, flavors and the like. Solid forms may include, for example, any of the following ingredients, or compounds of a similar nature: a binder such as microcrystalline cellulose, gum tragacanth or gelatine; an excipient such as starch or lactose, a disintegrating agent such as alginic acid, Primogel, or corn starch; a lubricant such as magnesium stearate; a glidant such as colloidal silicon dioxide; a sweetening agent such as sucrose or saccharin; or a flavoring agent such as peppermint, methyl salicylate, or orange flavoring.

[0348] Injectable compositions are typically based upon injectable sterile saline or phosphate-buffered saline or other injectable carriers known in the art. As above mentioned, the pyrrolidine compounds of formula I in such compositions is/are typically a minor component, frequently ranging between 0.05 to 10% by weight with the remainder being the injectable carrier and the like.

[0349] The above described components for orally administered or injectable compositions are merely representative. Further materials as well as processing techniques and the like are set out in Part 8 of Remington's Pharmaceutical Sciences, 17Edition, 1985, Marck Publishing Company, Easton, Pa., which is incorporated herein be reference.

[0350] The compounds of this invention can also be administered in sustained release forms or from sustained release drug delivery systems. A description of representative sustained release materials can also be found in the incorporated materials in Remington's Pharma-ceutical Sciences.

[0353] Commercial (2S,4R)-1-(tert-butoxycarbonyl)-4-hydroxy-2-pyrrolidinecarboxylic acid (30 g, 0.13 mol) was dissolved in acetone (1500 ml). A mechanical stirrer was placed in the flask and the solution stirred vigorously. A freshly made solution of 8N chromic acid was prepared by dissolving chromium trioxide (66.7 g, 0.667 mol) in water (40 ml), adding concentrated sulphuric acid (53.3 ml) and adding enough water to bring the solution volume to 115 ml. The 8N chromic acid solution (115 ml) was then added dropwise over a period of 30 minutes with continued vigorous stirring, the reaction's exotherm being maintained at the optimal temperature of 25° C. by the use of an ice bath. After the complete addition of the chromic acid, the reac-tion mixture was stirred for a further 15 minutes—maintaining the optimal temperature of 25° C. The reaction mixture was then quenched by the addition of methanol (20ml). Exotherm controlled by the use of an ice bath and, if necessary, direct addition of a small amount of crushed ice to the reaction mixture itself. The reaction mixture was filtered through a Celite pad and then concentrated in vacuo. The resulting acidic solution was then extracted with ethyl acetate (3×300 ml) and the combined organic layers washed with brine (2×100 ml). Organics then dried with magnesium sulfate and concentrated in vacuo. Crude product recrystallised from Ethyl acetate to give the white crystalline product, (2S)-1-(tertbutoxycarbonyl)-4-oxo-2-pyrrolidinecarboxylic acid (22.55 g, 76%). The antipodal intermediate, (2R)-1-(tert-butoxycarbonyl)-4-oxo-2-pyrrolidinecarboxylic acid, was made according to the same protocol, starting from commercial (2R,4S)-1-(tert-butoxycarbonyl)-4-hydroxy-2-pyrrolidinecarboxylic acid.

Example 22 General Protocol for the Solid-Phase Synthesis of Pyrrolidine Derivatives of General Formula I.

[0483] a) Loading step

[0484] Kaiser oxime resin (16.5 g, loading 1.57 mmol/g) was added to a solution of the relevant pyrrolidine carboxylic acid building block (51.8 mmol) and diisopropylcarbodiimide (8.1 ml, 51.8 mmol) in dry dichloromethane (150 ml). The resulting suspension was shaken over-night before filtering at the pump and washing sequentially with DMF, DCM and finally diethyl ether before drying at room temperature in vacuo.

[0485] b) N-deprotection Step

[0486] The resin obtained in the loading step was shaken with a 20% solution of trifluoroacetic acid in dichloromethane (200 ml) for 30 minutes prior to filtering at the pump and washing sequentially with aliquots of DMF, DCM and finally diethyl ether before drying at room temperature in vacuo.

[0487] c) N-Capping Step

[0488] The resin from the previous step was transferred into a 96-well filter-plate (approx. 50 mg of dry resin/well) and each well treated with an N-reactive derivatising agent, e.g. with either of the following solutions:

[0489] a) an acid chloride (0.165 mmol) and diisopropylethylamine (0.165 mmol) in dry dichloromethane (1 ml), overnight

[0490] b) an acid (0.165 mmol) and DIC (0.165 mmol) in, depending on the solubility of the carboxylic acid, dry dichloromethane or NMP (1 ml) overnight.

[0491] c) an isocyanate (0.165 mmol) in dry THE (1 ml), overnight

[0492] d) a sulfonyl chloride (0.165 mmol) and diisopropylethylamine (0.165 mmol) in NP (1 ml), overnight

[0493] e) a benzyl (alkyl) bromide (0.165 mmol) and diisopropylethylamine (0.165 mmol) in NT, (1 ml), overnight.

[0494] f) a vinyl ketone (0.165 mmol) in THF, overnight

[0495] g) diketene (0.165 mmol) in THF, overnight

[0496] The plate was then sealed and shaken overnight at ambient temperature. The resins were then filtered, washing the resin sequentially with aliquots of DMF, DCM and finally diethyl ether before drying at room temperature in vacuo.

[0497] d) Cleavage Step

[0498] A solution of amine (0.05 mmol) in 2% AcOH in dichloromethane (1 ml) was added to each well containing the resin from the previous step. The plate was then sealed and shaken for two days at ambient temperature. The wells were then filtered into a collection plate and the solvent removed in a vacuum centrifuge to yield 2-3 mg of the corresponding products, generally obtained as oils. The products were characterised by LC (205 nm) and mass spectrometry (ES+). All of the following examples were identified based on the observation of the correct molecular ion in the mass spectrum, and were shown to be at least 40% pure (usually 60-95% pure) by LC.

Example 446 Biological Assays

[0934] a) Production of Recombinant Bax

[0935] Human Bax-α lacking 20 amino acids at the COOH-terminus is expressed as a GST fusion protein or a His-tagged protein in Escherichia coli, and the protein is purified from the soluble cell fraction. In brief, the GST-Bax fusion protein is applied to a glutathione-Sepharose column, and Bax was released by cleavage with thrombin (0.6U/mL). Bax is subsequently purified on heparin-Sepharose, followed by fast protein liquid chromatography (HPLC) Mono Q. His-tagged Bax is purified on a Ni-nitriloacetic acid-agarose column followed by HPLC MonoQ:

[0936] b) Isolation of Mitochondria

[0937] Mitochondria are isolated from mouse liver cells by differential centrifugation. Cells are broken with a dounce homogenizer and the suspension is centrifuged at 2,000 g in an Eppendorf centrifuge at 4° C. This procedure is repeated until almost all the cells are broken. 20 Supernatants from each step are pooled before centrifugation at 13,000 g at 4° C. for 10 min. The pellet is resuspended in 40 mL MB buffer and centrifuged at 2000 g for 2 min. The supernatant is removed and centrifuged at 13 kg for 4 min. The mitochondria are recovered in the 13k pellet and resuspended in MB buffer at a density of 30 OD600 nm/mL.

[0938] c) In Vitro Assay for Cytochrome c Release

[0939] Mitochondria (30 μg) from mouse liver are incubated with 200 nM recombinant Bax in the presence of various compounds (5 μM) in 200 mL of KCl buffer for 20 min at 30° C. and are then centrifuged for 4 min at 13,000 g at 4° C. Mitochondrial pellets corresponding to 1.5 μg proteins are separated by SDS-PAGE using 4-20% Tris-Gly gels (NOVEX) and their respective contents of cytochrome c are estimated by Western blotting using polyclonal anti-cytochrome c antibody (dilution 1:2,500). Antigen-antibody complexes are detected using horseradish peroxidase-conjugated goat anti-rabbit IgG and enhance chemiluminescence detection reagents. The cytochrome c bands are scanned and quantified using a Bio-Rad (GS-700 Imaging Densitometer).

[0940] d) Effect of Compounds According to Formula I onto the Release of Cytochrome c Trig-gered by Bid-Induced Bax Activation (In Vitro Assay)

[0941] Concerning the Bid-induced activation of Bax leading to mitochondrial Cytocbrome C release, it is referred to the description of Martinou et al. in The Journal of Cell Biology, Vol. 144, No. 5, Mar. 8, 1999, pages 891-901. Mitochondria isolated from HeLa cells are incubated for 15 min at 30° C. in 100 μl of KCl buffer in the presence or absence of 10 nM recombinant Bid. The various compounds (10 μM) are pre-incubated for 5 min prior to addition of Bid. Following incubation, mitochondria were centrifuged for 5 min at 13000 g at 4° C. and the supernatant is collected for cytocbrome c analysis. Cytochrome c is detected by Western blotting. The cytocbrome c bands are scanned and quantified using a Bio-Rad (GS-700 Imaging Densitometer).

[0942] The above set out 2 in vitro assays c) and d) involving the determination of mitochondrial cytochrome c release are based on immunochemical methods using the Western blot analysis. Alternatively, said quantitative cytochrome c determinations may be performed by using spectrophotometric means:

[0943] I. by recording the difference between reduced and oxidised cytochrome c by dual wavelength double beam spectrophotometry;

[0944] II. by measuring the rather intensive γ or Soret peak in the spectrum of cytochrome c (ε=100 mM⁻¹cm⁻¹) is used for rapid and quantitative determination of the release of cytochrome c from isolated mitochondria This technique allows a highly convenient, fast and reliable quantitative determination of the release of cytochrome C.

[0945] e) Sympathetic Neuron Culture and Survival Assay (In Vivo Assay)

[0946] Sympathetic neurons from superior cervical ganglia (SCG) of newborn rats (p4) are dissociated in dispase, plated at a density of 104 cells/cm² in 48 well MTT plates coated with rat tail collagen, and cultured in Leibowitz medium containing 5% rat serum, 0.75 g/ml NGF 7S (Boehringer Mannheim Corp., Indianapolis, Ind.) and arabinosine 105M. Cell death is induced at day 4 after plating by exposing the culture to medium containing 10 g/ml of anti NGF antibody (Boehringer Mannheim Corp., Indianapolis, Ind.) and no NGF or arabinosine, in the presence or absence of pyrrolidine derivatives inhibitors according to formula I. 24 hours after cell death induction, determination of cell viability is performed by incubation of the culture for 1 hour, at 37° C. in 0.5 mg/ml of 3-(4,5-dimethyl-thiazol-2-yl)-2,5 diphenyl tetrazolium bromide (MTT). After incubation in MTT cells are re-suspended in DMSO, transferred to a 96 MTT plate and cell viability is evaluated by meas-uring optical density at 590 nm.
